PLow-HARRow. I

WALTERS, a

useful Improvements in Plow-Harrows, of

which the following is a specification.

My present invention relates to plow harrows particularly adapted for connection with the plow, to move w 1th the same, to pulverize the ground as it is plowed;

The principal objects of my invention are to provide a harrow adapted for attachment .to the beam or other framemember of an agricultural implement, whereby it may be set to operate at a predetermined adjusted position relative to sald implement; to

provlde means for adjusting the pressure upon the harrow, to enable it to successfully perform its function; to adapt the draw frame of the harrow for supporting the frame of the soil-working elements according to the-size of the latter; and 1n general,

- to provide a harrow which is simple in con- I struction, and hence inexpensive to manufacture. v

Another object of my invention is to. provide a harrow which will not oscillate-to anyv material extent relative to the implement to which it is attached.

4 Other objects of my inventlonwill appear in the following detailed descript on, taken in connection with the accompanylng drawing forming a part of this specification, and

in whichdrawing: j

Figure 1 1s a plan vlew of'the harrow embodying my invention, and showing its application to a member of an agricultural implement. Fig. 2 is a sectional v1ew on the line 22 of Fig. 1. Fig. 3 is a fragmentary detailed view showing means for retammg the draw frame in a relative to the draw-bar of theharrow.

In the drawing where similar characters refer to similar parts, 4 designates a frame member of an agricultural implement, such. as a gang plow. To this frame member 1s secured a draw-bar 5, and a brace 6 may be provided, operatively connecting the'drawbar 5 and frame member 4, to retain the same rigid with the latter. The drawbar 5 carries a draw frame 7, preferably pivoted thereto as by a bolt 8. The frame 7 may be retained in a rigid adjHStGdPOSItIOH relative to bar 5, as by co-acting clamps 9 and 10, which clamps are carried by mem- Specification of Letters. Patent.

bers 7 and 5 respectively. The draw frame preferably includes a cross-bar 11, carry- .lng downwardly extending arms 12, disposed 'in spaced apfartrelation to each other. Each arm 12 is provided with a plurality 'oftransverse apertures 13 disposed longitudinally thereof, for a purpose to be subsequently set forth. I provide aframe 14, preferably symmetrically of frame 7, adapted to carry soil working or harrowing members 15. As disclosed in Fig. 1, this frame is preferably Vshaped,to be drawn with its apex foremost. The frame 14 is operatively connected with draw frame 7' as by drag meansdes'ignated generally by, 16. This drag means preferably comprises a U- shaped member, the arms 17 of which have trunnion-like projections 18 fitting into the apertures 13 inarms 12, and having securing means 19, such as cotter-pins passing through saidprojections 18. The cross-rod 20 of this means is pivotally connected to frame 14 as by eye-bolts 21 surrounding the same. i The arms 17 may be held in rigid spaced apart relation to each other, as by a T-shaped brace 22, which rigidly braces the dragmeans. The draw frame 7 may include a rearwardly projecting yoke 24, having a transverse aperture 25, fora purpose to be subsequently ,set forth. Thisyoke carries pressure imposing means 26 for cooperation with frame-1'4. This means preferably comprises a bracket 27 adjacently carried by yoke 24, and apertured at 28; a rod extend ing through aperture 28 and having an eye 30 at its lower'end;

sides of and, two .coil springs 32- about spring a each side bracket 27'; rod 28, one

cured thereto, as by eye 30 receiving a hook 38 carried bythe latter, and preferably in advance of the pivotal connection of drag By manipulating the abutments 31, the degree of pressure upon the frame 14 may be adjusted. The bracket 27 is adjustable vertically of frame 7 as by having two parallel portions 34 provided with a plurality of pairs of alined apertures35, one pair of which may register withaperture 25 in yoke 24, to receive a bolt 36. By this arrangement, the frame 7, as well as the pressure imposing means 26 may force frame 14 downwardly by beingfseadjustable collars or of the bracket 27, at" which ,they abut, and one confined between,
